Step Frequency High PRF Waveform Design.
Abstract
This report discusses the design and analysis of a step frequency waveform for a surface based radar to detect small targets embedded in clutter. Detection of small targets requires significant reduction in clutter which can be achieved with high range resolution radar with narrow range cell size and Doppler processing. High range resolution with conventional constant frequency waveforms requires high speed A/D with large dynamic range, which is limited by existing A/D technology. However, step frequency allows high resolution with modest A/D requirements. The design of a step frequency waveform is complex due to the conflicting effect of waveform parameters on performance goals. In this report, the design process which determines the waveform parameters for given radar specifications, is systemized. A graphical as well as a computer implementation of the design process is presented. The step frequency waveform is analyzed using the ambiguity function which brings out the characteristics and advantages of the waveform. The ambiguity surface and related diagrams are plotted for specific waveforms of interest.
